FEATURES
Target Corporation's lightweight, portable Pulse Generator is intended for use with AIMS systems that do not include the required IFF Pretrigger for Mode 4 identification.
The SG-1066/UPX provides the function of enabling the Mode
4 time decoded video to be aligned, in time, with both radar and
SIF vide0. The effect upon the system is to cause the Mode 4 processing
to appear to be in response to a Mode 4 Pretrigger. The alignment,
or pretrigger time, is adjustable via thumbwheel switches on the
front panel in increments of 1 us from 0 to 999 us. An internal
crystal controlled clock allows for an alignment accuracy of ±0.5
us independent of the front panel switch settings. Both video
and trigger inputs are thresholded to allow for operation in a
non-ideal environment and to provide for highly reliable output
data.
A slide-out chassis, modular circuit card assemblies and platform
mounting enable convenient servicing. All input/output connectors
are mounted on the rear panel and connectors are provided on the
front panel for signal monitoring.
